Built for New York
What we handle for you
Alteration agreements
Drawings, scope letter, schedule, insurance certificates naming the building and managing agent, and responses to the board’s architect.
DOB permits
Most kitchen and bathroom renovations with plumbing, gas or electrical changes need an ALT2 filing by a licensed architect or engineer. We coordinate filing, inspections and sign-offs.
Environmental testing
Buildings built before April 1, 1987 need an asbestos investigation before DOB permits are issued, and pre-1978 buildings need lead-safe work practices.
Building logistics
Elevator bookings, protected hallways, permitted work hours and debris removal, managed so your neighbors and super stay on side.

FAQ
NYC renovation questions
Which parts of New York City does BDM work in?
Manhattan, Brooklyn and Queens, including the Upper East and West Sides, Harlem, Midtown, Chelsea, the Village, Tribeca, Brooklyn Heights, Park Slope, Cobble Hill, Williamsburg, Long Island City and Astoria. Our office is at 534 Madison Avenue in Midtown.
What license does a NYC renovation contractor need?
Contractors doing home improvement work on residential property in New York City need a Home Improvement Contractor license from the Department of Consumer and Worker Protection (DCWP). Contractors who pull DOB work permits also need to be registered with the Department of Buildings, and plumbing and electrical work must be done by DOB-licensed master plumbers and electricians.
How long does co-op board approval take?
It varies by building. Many boards and their architects take several weeks to review an alteration package, and complex projects with plumbing changes take longer. Submitting complete drawings, insurance certificates and schedules the first time is the biggest time-saver.
Do you work in landmarked buildings?
Yes. Uptown 388 was a historic brownstone restoration. Work on designated landmarks and in historic districts generally needs Landmarks Preservation Commission approval alongside DOB permits; we plan for that review.
